The
Tundra 2 has a nice little whine to it that will
make it stand out in the case. The pitch is mid-level, and audible from a few feet away. Listen
to this heatsink in operation for yourself by clicking on the headphones and playing the MP3
recording.

Sound Level
Measurements:

Listening to the actual noise a heatsink makes
allows you to hear what pure numbers alone cannot get across. To further
emphasize FrostyTech's reliance on cold hard facts when evaluating a heatsink,
we also take Decibel readings with a sound level meter. These results may be
higher than the manufacturer's listed specs, but then again these are real world
measurements.

As we
mentioned, the AVC Tundra 2 has a bit of power to its fan, and it is for this reason that the Tundra 2
comes in at 58.4 dB in our measurements. For office environments this isn't a problem,
but for 24/7 bedroom computers it may be too much to bear for some
people.
